Nobody really knows precisely how long the Naysayers have been around. They probably can trace their origins back any of a dozen among several hundred minor thief gangs that have sprung up and faded away within Leoden, but it is known that they came to control the Thieves Gate around twenty summers past. Previous to that summer the Thieves Gate had been run by a gang referred to as the Joykills. However, on Midsummer's Night, the windows and spaces under doors and the cracks between stones and boards were all seen to shoot out a bright sickly green light. The light lasted for several hours, and nobody dared approach the building. Nothing could be heard within. The next morning, nothing, not a single living person could be found within the Thieves Gate.
The Naysayers moved in before anyone else was willing to, and have been there ever since.
The leader of the Naysayers is a human named Thome d'Arg. Thome is tall, and rail thin, with a severe scar running over his eye and down past his lips. (People debate whether the eye is real or not; it looks real enough but most people are not willing to ask.) His hair is a dark, coal black, and he is always seen playing with a long, slim, expertly made dagger.
How many Naysayers there actually are in the city is hard to say, but those who care for such things estimate that there can be no more than twenty or thirty.
